allows for the free-passage of the contents of the tube therefrom when the valve cap is disposed in open position, but when disposed in closed position, keeps the contents of the tube in a fresh, clean and sanitary condition. 1

Another object of the invention is to prom operation and service and provides a eole lapsible tube that is convenient to use. This invention also consists in certain other features of construction and in the combination and arrangement of the sev eral parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a view illustrating one form of my invention with the valve cap arranged in open position.

Figure 2 is a similar view with the cap disposed in closed position.

Figure 3 is a sectional view taken through the ca and showing parts in elevation and with t e cap in open position.

Figure 4 is a similar view with the cap in closed position.

Figure 5 is a sectional view taken approximately on line 55 of Figure 1.

Figure 6 is a sectional view taken approximately on line 66 of Figure 2.

Figure 7 is a sectional view taken approximately on line 7-7 of Figure 6.

Figure 8 is a detail perspective view of the spring disk which forms a part of the present invention.-

. Figure 9 is a detail view of the cap per se.

7 Figure 10 is a sectional view illustrating a modified form of my invention with the parts in open position.

a Figure 11 is a similar view with the parts in closed position,

Figure 12 is a fragmentary view illustrating the neck of the collapsible tube with a groove formed therein. vide a. valve cap for collapsible tubes that f is reasonably simple in construction, inexi pensive to manufacture, extremely efiicient tube, and? the cap which as shown is provided with a skirt and which has formed with its upper edge a bead 3 that is serrated so as to provide'for the easy rotation of the cap as will be apparent. x

The neck 1 is provided with a slot disposed horizontally therein and following the curvature thereof as best shown in Figures 5 and v 6,;and this slot which is indicated by the reference numeral 4 Pas arranged at its ends, recesses 5 extending beyond the upper edge of the slot as best shown in Figure 3. The

cap 2 is likewise provided with a slot 6 which is formed by cutting metal'therefrom and turning a portion ofthe cut metal inwardly to provide a sto lug 7 that is engageable with the ends. 0 the slot 4 and within the '0 recesses 5, when the cap 2 is disposed to either its open or closed position as shown in Figures l and 2 of the drawings.

Arranged on the top of the neck 1 and disposed between the same and the top of the cap 2 is a disk 8 that is formed from spring metal and has cut therefrom a spring 9 which engages the top of the cap 2, and therefore urges the latter upwardly as will be apparent upon inspection of Figure 3. By providing this disk and spring finger 9, it will be obvious that the spring finger will hold the stop lug 7 in either of the recesses 5 and therefore casual rotation of the cap 2 will be prevented.

In the forms of the invention as shown in Figures 10 to 14 inclusive the reference numeral 10 indicates the neck of the tube which as shown is provided with a slot 11 and the cap 12 is also provided with a slot 13 that is adapted to registen with the slot 11 when the cap 12 disposed to open position as shown in Figure 10. The neck 10 is provided with a groove 1--t disposed circumferentially of the neck 10 and this groove has arranged therein substantially V-shape in cross section vertically disposed channels 15 which are adapted to receive the free end of a dog 16 of substantially T-shape formation as shown in Figure 14. This dog has its opposite or enlarged end secured within a groove 17 of the same shape as the dog, and the groove 17 is formed in the inner wall of the cap 12 as shown in Figure 13.

\Vhen the cap is arranged as shown in Figure 10, the slots 11 and 13 register, and the dog has its free end engaged within one of the V-shape channels, but when the cap is arranged as shown in Figure 11, the slots 11 and 13 are out of registration and the free end of the dog 16 is arranged in the other channel 15, with the result that the cap 12 is held in either its open or closed position with out fear of casual movement thereof.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

\Vhat I claim is:

1. In a collapsible tube including a neck having a slot formed therein, a cap mounted for rotation on said neck and having a slot adapted to register with the slot of the neck, whereby the contents of the tube can be dispensed, said neck having a groove arranged circumfcrentially therein and having channels disposed within the groove, means carried by said cap for engagement in the channels for holding the cap in positions whereby the openings are disposed in or out of registration.

In a collapsible tube including a neck having a slot formed therein, a cap mounted for rotation on said neck and having a slot adapted to register with the slot first mentioned, said neck having a groove disposed circuniferentially therein, said. groove havin channels V-shape in cross section dispose in spaced relation with respect to each other, a dog carried by the cap", and having its free end disposed for engagement in the channels for holding the cap in positions whereby the slots will be disposed in or out of registration.

In testimony whereof I aflix my signature.

CHARLES FOTI.
